  • Patent number: 11936813
    Abstract: A request for a contact center agent interaction is received from a user device associated with a user. The user device is connected to a virtual waiting room according to a connection mode that is selected from a set that includes a private connection mode. The private connection mode enables the user to observe communications of at least a subset of waiting users of a contact center queue and hides a presence of the user from the waiting users. Responsive to an indication to activate a private session between the user device and an agent device associated with a contact center agent, the user is removed from the virtual waiting room.

  • Publication number: 20240089373
    Abstract: A software platform includes emergency event processing functionality for detecting and mapping emergency event occurrences. The emergency event processing includes call path processing for concurrently routing an emergency call from a device registered with the software platform for a customer thereof to a public safety access point and to a monitoring device of the customer. The concurrent routing enables an operator of the monitoring device to join the emergency call, for example, by monitoring the call to determine how to notify other operators of the customer of the subject emergency event or by participating in the call to assist in the emergency event response. The concurrent routing may further automate, and therefore expedite, the signaling of an emergency event to others at the location of the emergency event, such as to prevent further risk of harm.

  • Publication number: 20230336658
    Abstract: A disconnection of a client device is disconnected during a multi-participant communication, such as a call or a conference. An indication of the disconnection is transmitted to the client device to cause an agent at the client device to record media locally at the client device. The media recorded by the agent at the client device based on the indication of the disconnection is later received and included within a recording of the communication. For example, a gap of the recording in which the disconnection occurred may be identified, such as by performing a comparison of media within the recording to identify a start time of the gap and an end time of the gap. The media is then inserted within a portion of the recording of the multi-participant communication corresponding to the gap.

  • Publication number: 20230144916
    Abstract: Location determination and telephone number distribution for emergency calls is enabled by a telephony system which maintains multiple pools of telephone numbers. Each pool corresponds to a different region such that the pools of telephone numbers are defined at the region-level rather than at the site-level. The telephony system determines the location of a calling device initiating an emergency call regardless of whether the calling device is at a known site. Based on the determined location of the calling device, one of the pools of telephone numbers which corresponds to that location is selected. The telephony system thereafter distributes a telephone number for the calling device to use for the emergency call from that selected pool of telephone numbers to facilitate an emergency call between the calling device and a local public safety answering point.

  • Publication number: 20230145272
    Abstract: A conference service number system enables the reconfiguration of an existing telephone number as a service number usable for selectively routing calls to each of a client endpoint and a dedicated conference software instance. A conferencing system implements separate conferencing software instances for individual operators for whom unique telephone numbers, are assigned. A telephony system facilitates calls to and from telephone numbers and implements a menu system (e.g. an interactive voice response (IVR) menu) for presenting a caller with options to either route a call to a specific telephone number to the subject operator (e.g., to a client device of that operator) or to a conferencing software instance implemented specifically for that operator. The call is accordingly routed to either a device of the operator or to the conferencing software instance based on the selection by the caller.
